Back to the Future II is the best explanation of closures I've ever seen.
- colanderman 15y agoI consider myself well-versed on both closures and BttF II but I don't understand this comment. Care to explain?
- rgrove 15y agoI'm referring to the scene in which Doc draws a diagram on a blackboard to explain to Marty why the two of them still exist even though they've screwed up history and created an alternate 1985. Essentially, they exist because they're in a time closure and they carry their own pasts with them into 1985-B. It's not a perfect analogy, but it's close enough that I've been able to use that scene to help make closures click for someone who was having trouble understanding them.
